This bar chart summarizes sales data from a sample CSV file loaded from GitHub, showing total sales per year in an SVG chart alongside an HTML data table. The page uses D3 v7 to fetch and parse the remote CSV, aggregate sales by `YEAR_ID`, and render the visualization with `d3.select`, `d3.scaleBand`, and `d3.scaleLinear` to create bars and axes. The summary table above the chart displays the same yearly totals, offering a textual counterpart to the graphical presentation.
